Something that recently caught my attention was the slowing of light particles - and keeping them slow. Light naturally slows when passing through transparent mediums, it is only in a vacuum that light move at it's true speed. By passing light through a mask made of transparent liquid crystals length wise, which changed the shape of the photons themselves, a team of scientists were able to keep the photons slow. Though not by much, they were constantly slower than natural light with unshaped photons (when passed through the same medium). This concept is a completely new concept, so I'm not sure where this could lead. Do you have any thoughts/ideas/speculations as to what this could lead to in the future?
